Where your data lives
Everything Mastery HQ stores lives on your PC, in inspectable formats. The app has no content servers: your code, prompts, transcripts, keys, and layouts never leave your machine except through the agent CLIs and model providers you configured with your own accounts.
The map
Section titled “The map”| Data | Where | Format |
|---|---|---|
| API keys | .env in the app’s local data folder (path shown in Settings → Agents) |
plain env file |
| Workspaces, layouts, themes, prefs | local app storage | JSON |
| Agent profiles (history, skills, backlog, notes) | agents/ in the app’s config folder |
one JSON per agent |
| Workspace project files (screenshots, whiteboards, assets) | the per-workspace folder (path shown in the workspace chooser) | regular files |
| Audit log | local app storage; exportable | JSON |
| Theme add-ons | app data (survive updates) | files |
What goes over the network
Section titled “What goes over the network”- Your agents’ traffic: prompts/completions between the agent CLIs (or OpenRouter) and the providers you signed up with — governed by those providers’ terms, not routed through Mastery HQ.
- Integrations you connect: Spotify auth (in your browser, to spotify.com), OBS/Streamlabs (loopback on your own PC), update checks to the release server.
- Feedback: only what you type into the Feedback form, when you send it.
Extra protections
Section titled “Extra protections”Key inputs are password-masked; Streaming Mode adds render-time secret redaction; keys and streaming passwords are excluded from the portable setup file by design.
